Abstract
A method of detecting impact damage of a structure having a first surface exposed to potential impacts from an object comprises providing a sensor having a body portion that has a surface provided with an elongated channel. The sensor is fixed to a second surface of the structure such that a conduit is formed by the channel and the surface. The surface is on an opposite side of the structure to the first surface. A pressure differential is established between the conduit and a reference pressure adjacent the conduit. Monitoring is conducted for detecting any change in the differential pressure that may be indicative of a fracture or crack propagating in the second surface.
